...-> other stuff not relevant in this case
this is part of a project which was working and which i'm refactoring
i've used include guards in every a.h, b.h, etc.
i just removed some unused functions from it up to now.
i don't understand what the cause of the problem might be.
whenever i try to compile i get the message:
unknown type name 'a_t' for b.h
however, in the project i've used the same technique in several places and
the compiler doesn't seem to complain.
i've used a_t* in the same exact way in other files (c.h, d.h, etc.)
and i don't have any problem there.
in b.c i include first a.h, then b.h, does the order matter?
i never import a .h in another .h
i extensively searched before asking.
what am i doing wrong here?
maybe circular import dependencies?
maybe the compile order? does it matter?
thank you
